Appears in sequences

• Number of partitions satisfying 0 < cn(2,5) + cn(3,5).at n=41A039897
• a(0)=0, a(1)=1, a(n) = smallest prime >= a(n-1) + a(n-2).at n=22A055498
• a(0)=0, a(1)=1, a(n) = smallest prime > a(n-1)+a(n-2).at n=21A055499
• Apart from initial 0, same as A055498.at n=22A073021
• Each term is the smallest prime > the sum of the previous 2 terms.at n=21A073022
• a(n) is the smallest prime used as initial value for Euclid-Mullin (EM) sequence (of variant A000945), such that in the corresponding EM-sequence the p=3 prime arises at the n-th position.at n=9A093780
• Smallest prime p such that p == 1 (mod prime(n)) and not p == 1 (mod k) for 2 < k < prime(n).at n=32A116605
• Primes q of the form a^3+b^2, such that p =A130467(n)= a^2+b^3 is prime and smaller than q; p < q ; b < a.at n=23A130468
• a(0)=0, a(1)=1; for n>1, a(n) = a(n-1)+a(n-2), except where a(n-1) is a prime greater than 2, in which case a(n) = a(n-1)-a(n-2).at n=37A376930
